My favorite tip is to simply record. The more you record — and listen to what you’ve recorded! — the more you come figure it all out.
Working together with other soundies, either going through movies and spotting sfx, brainstorming on sculpting the movies feel and soul in sound, or being on recording sessions with other people inspires me a lot. ~ Mikkel Nielsen
Try everything, read articles about your craft, always keep your ears open and your portable recorder working. Love what you do, and it will definitely pay off.
